基于hp自适应伪谱法的多脉冲导弹弹道优化设计
Optimizing design of trajectory for multiple-pulse missiles based on hp-adaptive pseudo-spectral method
摘要
Abstract
According to the characteristics of the discontinuous boost for multiple-pulse missiles, the multi-constraints and multi-phase trajectory optimization problem based on hp-adaptive pseudo-spectral method was researched.The trajectory segment cri-terion was presented combining with the missile working process. The dynamic model and multi-constraints multi-phases trajectory optimization model were established concerning the constraints of overload,dynamic pressure,and terminal trajectory parameters.A maximum range optimization calculation case based on hp-adaptive pseudo-spectral method solving strategy was given,so as to tackle the constraints when using Radau,pseudo spectral method to deal with complicated optimization problem.Moreover,the results were compared with that of the traditional maximum lift-to-drag ratio method.The simulation results show that the algorithm can efficiently solve the problem of multiple-pulse missile trajectory optimization and improve the maximum range by 7. 8% in comparison to the maximum lift-to-drag ratio method. The results can provide a reference to the overall design of multiple-pulse missiles.关键词
